Facing the Deep: A Photographer's Encounter with a Living Fossil 

The vast expanse of the ocean holds countless mysteries, with hidden creatures lurking in the depths. However, the quest to document these elusive animals often presents a significant challenge – venturing into the abyss can be a perilous undertaking. But for some intrepid photographers, the desire to capture these marvels on film outweighs the inherent risks. Enter Laurent Ballesta, a fearless underwater photographer who has pushed the boundaries of exploration to bring us face-to-face with a living fossil – the coelacanth. 

In 2010, Ballesta embarked on a remarkable journey off the east coast of South Africa. Descending into the inky blackness of Sodwana Bay with his camera equipment, a sense of anticipation hung heavy in the air. His mission? To capture the first-ever photograph of a living coelacanth in its natural habitat. These ancient fish, once thought to have vanished alongside the dinosaurs, were a living testament to the power of evolution. 

A Journey Through Time: The Coelacanth's Enduring Legacy 

Travel back to the age of the dinosaurs, and the coelacanth would have been a common sight. These lobe-finned fish thrived in the shallow waters of the Triassic Period, inhabiting the planet for a staggering 410 million years. Notably, coelacanths belong to a group that served as a precursor to tetrapods – the group encompassing all land-dwelling vertebrates like amphibians, reptiles, birds, mammals, and yes, even us humans. This connection makes the coelacanth a crucial missing link in the evolutionary chain, highlighting the kinship between land and sea creatures. 

Fossil evidence suggested that the coelacanth became extinct around 66 million years ago, alongside the dinosaurs. However, this notion was shattered in 1938 when a fisherman off the coast of South Africa inadvertently hauled up a living coelacanth in his trawl net. This unexpected discovery earned the coelacanth the nickname "living fossil," although scientists now acknowledge this term is slightly misleading. While coelacanths haven't undergone dramatic evolutionary changes, they have certainly adapted to their deep-sea environment. Their once shallow-water habitat has been swapped for the inky depths, a testament to their remarkable resilience.

The Elusive Quarry: Unveiling the Coelacanth's Hidden Realm 

Capturing a living coelacanth on film proved to be a formidable task. These elusive fish dwell in the benthic zone, residing on the seafloor at depths exceeding 300 meters along underwater slopes and shelves. During daylight hours, they seek refuge within the darkness of submarine caves, emerging solely to hunt under the cloak of night. It was within these very caves that Ballesta would finally come face-to-face with his long-sought quarry. 

The journey, however, was fraught with danger. The coastline surrounding the caves was notorious for its rough swells, strong currents, and, of course, sharks. These hazards were a stark reminder that venturing into the deep could have devastating consequences. Undeterred by the risks, Ballesta's unwavering passion for ocean exploration fueled his determination. 

Beyond the Surface: A Life Dedicated to Exploration 

Driven by a childhood dream to push the boundaries of ocean exploration, Ballesta had dedicated his life to becoming a multi-faceted ocean advocate. He skillfully combined his expertise as a marine biologist with his adventurous spirit, mastering the art of deep-sea diving to pursue groundbreaking underwater photography. This unique blend of skills allowed him to not only capture stunning visuals but also contribute valuable scientific data. 

So, why take such a perilous risk? According to Ballesta, traditional methods of exploration using remotely operated vehicles (ROVs) were simply inadequate. ROVs, while technologically advanced, are inherently slow and lack the agility of a human diver. In Ballesta's case, it took his dive team a mere 12 minutes to survey all the relevant caves, whereas an ROV would have required a grueling four hours. Additionally, ROVs are limited in their maneuverability, unable to navigate the intricate crevices and corners within the caves. 

"Of course," Ballesta acknowledges, "exploring depths exceeding 1,000 meters is beyond human capabilities. But for the twilight zone, where depths range from 200 meters onwards, we are far more efficient." 

This efficiency proved to be crucial. Within the first minute of his initial dive, Ballesta found himself face-to-face with a coelacanth. The true challenge, he explains, wasn't locating the fish itself, but rather immersing himself in its mysterious world. 

An Encounter in the Twilight Zone: Illuminating the Coelacanth's World 

The initial encounter with the coelacanth wasn't one of awe-inspiring curiosity, according to Ballesta. The fish displayed neither a sense of fear nor an eagerness to investigate the imposing figure hovering before it. However, Ballesta and his team had a plan. By carefully positioning the coelacanth between two strategically placed cameras, they hoped to encourage some movement and capture the elusive fish in all its glory. 

But before achieving that goal, they needed to address the lighting situation. One might assume that the depths of the ocean are shrouded in perpetual darkness. While that's true for extreme depths, the twilight zone, where coelacanths reside, receives a faint sliver of light that filters down from the surface. This light, though minimal, is crucial for Ballesta's photography. 

"It's important not to use too much artificial light," he explains. "At these depths, the natural light, though faint, is still present. Using excessive artificial light creates a similar effect to driving with your high beams on at night. While you see what's directly in front of you, everything else disappears into darkness. However, by turning off your headlights and relying on the moonlight, you can see the entire scene – the road, the mountains, the forest. The same principle applies in the deep sea." 

By utilizing minimal artificial light that mimicked the natural twilight, Ballesta was able to illuminate the coelacanth without disrupting its environment. This meticulous approach not only yielded stunning photographs but also ensured minimal disturbance to this ancient creature. 

A Return to the Deep: Unveiling the Coelacanth's Secrets 

Fueled by the success of their initial encounter, Ballesta and his team returned to the site in 2013. This time, they were fortunate enough to encounter not just one, but several coelacanths. The extended time spent observing these elusive creatures provided invaluable insights into their behavior. They documented the coelacanths' movements for up to 30 minutes at a time, piecing together a glimpse into their lives in the abyss. 

Ballesta's ultimate dream, however, extends far beyond fleeting encounters. He envisions returning to the coelacanths with a subsea station, a habitat that would allow him and his team to spend extended periods observing these living fossils in their natural habitat. Imagine a scenario where scientists could spend a full day and night alongside the coelacanths, meticulously documenting their behavior, feeding patterns, and social interactions. Such an endeavor would undoubtedly unlock a treasure trove of knowledge about these enigmatic creatures. 

The Ocean's Untold Stories: The Importance of Deep-Sea Exploration 

The quest to understand the coelacanth is just one chapter in the ongoing saga of deep-sea exploration. As Jessica Gordon, a marine scientist at the University of Essex, poignantly points out, "We know so little about the deep sea." Encompassing over 70% of the Earth's surface and containing a staggering 97% of all the water on the planet, the deep sea remains a vast and largely unexplored frontier. This hidden realm plays a critical role in regulating our planet's climate, absorbing a significant portion of human-caused carbon dioxide emissions and excess heat. Furthermore, the deep sea serves as the world's largest ecosystem, teeming with an incredible diversity of life. Experts estimate that a staggering 91% of ocean species remain unclassified, highlighting the immense potential for scientific discovery that lies beneath the waves. 

Gordon's recent participation in an expedition led by the global scientific program, Ocean Census, exemplifies the ongoing efforts to unravel the mysteries of the deep. The team ventured into previously uncharted territories of the seafloor off the coast of New Zealand, and their discoveries were nothing short of astonishing. Over 100 new species of deep-sea organisms were identified, including an array of fish, squid, mollusks, and even unique forms of coral. These groundbreaking discoveries underscore the sheer abundance and diversity of life that thrives in the hidden depths. 

Protecting the Deep Sea: Urgency and Unseen Consequences 

The urgency for continued exploration is undeniable. As Gordon warns, "Without knowing what's there, we could destroy areas that we have no idea are absolutely full of life – essential to the ecosystem and to the functioning of the seas. We'll never know what we could have saved." The potential consequences of unchecked human activity in the deep sea are dire. Habitat destruction, pollution, and the effects of climate change all pose significant threats to these vulnerable ecosystems. 

A Window into the Past: The Coelacanth as a Living Fossil 

The coelacanth, with its ancient lineage, represents a living bridge between the past and present. Every fossil unearthed is a piece of the intricate puzzle that narrates the story of evolution. However, to witness a living coelacanth swimming gracefully in its natural habitat is an awe-inspiring experience, according to Emma Bernard, curator of fossil fish at London's Natural History Museum (NHM). "You can directly compare the fossilized remains to the modern-day coelacanth," she explains, "observing the remarkable similarities between their bone structures and movements." 

While fossils and preserved specimens offer valuable insights, they can only tell part of the story. James Maclaine, a curator of fish at the NHM, emphasizes the limitations of studying solely these remains. "Fossils allow us to make educated guesses about a creature's behavior, but there are always unexpected surprises," he says. He cites the example of pelican eels, long, slender fish with cavernous mouths resembling a pelican's beak. Based solely on physical specimens, scientists assumed these eels used their large mouths for feeding. However, observations of live pelican eels in their deep-sea habitat revealed a fascinating twist. Researchers documented these eels inflating their heads like balloons when approached by submersibles, suggesting a potential defense mechanism to intimidate predators. 

The Art of Deep-Sea Photography: Facing Danger in Pursuit of Beauty 

So, what does it truly take to excel in the realm of deep-sea photography? According to Ballesta, it's the willingness to confront danger. "I've noticed a pattern," he says. "Whenever a dive is too easy, the resulting photographs are underwhelming. I need to feel a sense of unease, a push outside my comfort zone, to produce my best work. Placing me in a warm, shallow environment like the Red Sea wouldn't inspire me to create exceptional imagery." Conversely, in extreme situations where the risks are high, and time is limited, a primal instinct kicks in. 

"Suddenly, surrounded by this alien ecosystem, you realize you're a visitor in their world, granted a fleeting glimpse. The urgency to capture the scene intensifies. Everything else fades away; I'm completely immersed in the moment, focused solely on creating the best possible images." This state of heightened focus and awareness, he explains, was precisely what he experienced during his encounter with the coelacanth. Only after a safe ascent, with adrenaline levels subsiding, did Ballesta allow himself to relish the accomplishment and the scientific value of their work. 

Beyond the Coelacanth: A Pioneering Spirit Pushes Boundaries 

The coelacanth expedition served as a springboard for Ballesta's remarkable career. In 2019, he embarked on a groundbreaking project that involved living in a saturation chamber for a staggering 28 days. Imagine a pressurized yellow container, essentially a small room situated on a floating barge, mimicking the conditions found 120 meters below the ocean's surface. Confined within this limited space alongside three other divers, Ballesta embarked on a unique underwater exploration. 

This project, codenamed Gombessa I, pioneered a novel diving technique. A diving bell was tethered to the saturation chamber, allowing commercial divers to descend to significant depths for underwater construction projects while remaining connected to the chamber for safety. Ballesta, however, took a different approach. He utilized an electronically controlled rebreather, a sophisticated breathing apparatus that allowed him to detach from the diving bell and explore the depths autonomously. This feat marked a historic moment, making Ballesta the first person to undertake an untethered underwater exploration in the deep sea, akin to an astronaut performing a spacewalk. 

Throughout the 28-day mission, Ballesta and his team conducted daily explorations within the twilight zone, stretching from Marseille to Monaco. Their efforts yielded invaluable data and breathtaking visuals, illuminating the intricate ecosystems of the Mediterranean Sea.
